Condensate Trap Field Drain Attachment; Pressure Switch Tubing - Bryant 355MAV Installation, Start-Up, And Operating Instructions Manual

COLLECTOR BOX DRAIN TUBE
(BLUE AND WHITE STRIPED)
b. Install removed clamp and plug into UPPER collector box drain tube (blue label) which was previously connected to condensate trap.
c. Connect LOWER collector box drain tube (blue and white striped label) to condensate trap. Tube does not need to be cut.
d. Clamp tube to prevent any condensate leakage.
2. Inducer Housing Drain Tube:
a. Remove factory-installed plug from LOWER collector box drain tube (blue and white striped label).
b. Remove and discard UPPER (molded) inducer housing drain tube which was previously connected to condensate trap.
c. Install cap and clamp on UPPER inducer housing drain connection where molded drain tube was removed.
d. Use inducer housing drain extension tube (violet label and factory-supplied in loose parts bag) to connect LOWER inducer housing drain
connection to condensate trap.
e. Determine appropriate length, cut, and connect tube to condensate trap.
f. Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
Refer to Pressure Switch Tubing section for connection procedure.
C. Condensate Trap Field Drain Attachment
Refer to Condensate Drain section for recommendations and procedures.
D. Pressure Switch Tubing
One collector box pressure tube (pink label) is factory connected to the pressure switch for use when furnace is installed in UPFLOW or
HORIZONTAL LEFT applications. This tube MUST be disconnected and used for the condensate trap relief port tube. The other collector box
pressure tube (green label) which was factory connected to the condensate trap relief port connection MUST be connected to the pressure switch
in DOWNFLOW or HORIZONTAL RIGHT applications.
NOTE: See Fig. 11 or tube routing label on main furnace door to check for proper connections.
Relocate tubes as described below.
1. Disconnect collector box pressure tube (pink label) attached to pressure switch.
2. Extend collector box pressure tube (green label) which was previously connected to condensate trap relief port connection by splicing to
small diameter tube (factory-supplied in loose parts bag).
3. Connect collector box pressure tube (green label) to High Pressure Switch connection labeled COLLECTOR BOX.
4. Use remaining smaller diameter tube (factory-supplied in loose parts bag) to extend collector box pressure tube (pink label) which was
previously connected to pressure switch.
5. Route this extended tube (pink label) to condensate trap relief port connection.
